This invention relates to improvements in- The invention is part0 the connection of handle connections. ticularly applicable choke rod handles to Bowden wire control mechanism for the adjustment of carburetor valves or the like. A' device in whlch the structure herein disclosed is useful is shown in my co-pending application, Serial No. 79,760, filed January It has proven a comparatively difficult and expensive matter to provide. adequate connection between a Bowden wire and a handle rod within the limited confines of the tubular housing within which such a rod is adjustable.

It is the object of the present invention to provide a simple, novel and inexpensive form of connection suitable for this purpose and adapted to maintain the Bowden wirein axial alignment with nected, practically nated.

In the drawings:

Figure 1 is a cordance with this invention. 7 V

Figure 2 is an enlarged detail view in side elevation of the end of the Bowden wire.

Figure 3 is an enlarged detail view in plan of the end of the handle.

Figure 4 shows an venlarged fragmental section through the end of the handle to expose its construction. 7

Figure is a view similar to Figure 4 illustrating the manner of application of the Bowden wire to the handle.

Like parts are identified by the same refer-- ence characters throughout the several views.

The handle device in its entirety is desig-' nated by reference character 10 and includes a knob 11 and a rod 12. The wire at 13 is pushed or pulled byfthe handle through a flexible housing (notshown) to operate a control of some sort (not shown). The usual use for a device of this character is to operate the choke control of the carburetor of an automobile. The invention relates particu 7 1926,United States 7 Letters Patent No. 1,739,812 dated December' f I i whlch are ofiset laterallyto approximately the handleto which it is con-.- all backlash being elimi-v slde elevation of a handle and} Bowden wire operatively connected in ac-.- ,ment tocause the the wire to enter theopening 17.? With the larly the connection between the Bowden wire 13'and the rod portionl2of the handle.

. In order to make a. connectionin accordance with this invention, the handle rod 12 is-first channeledirom above and below at 14 and,15. These channels open to the end of the rod and the intervening web 16 is bored to'providean opening 17 afiording communication between the handles. p p

The Bowden wire has two portions 19and .matelyequal to the thickness of the web 516.

4T0 effect a connection between the "parts above described the Bowden. wire 13 has its end, 20 introduced through opening 17 inthe handle with the Bowden wire in approxl- {mately the relative positionwith respect to the handle in which it is illustrated in dotted @lines in Figure 1. The portion 20 having penetrated to'the limit 7 of movement possible thereto in this position. of the parts, the wire and handle are now manipulated into aligntransverse portion ,21 of parts in alignment, it ,will be foundthat the POi' iIQIlQO'of the wire win; lie along the up-.

per surface of web 16 and will be closely confined between the walls of channel 14 while the ortion 19 of the wire will abut the under sur ace of web 16 and will be closely confined between the walls of channel 15. As shown in Fig. 5 the diameter of the aperture 17 corresponds closely. with the diameter of the wire. The length of the offset 22is such that the unbent portions of wire 13 will be substan tially aligned withthe the center lineof web 16. The wire 13 and member 15 are maintained in their assembled relation by the tubular housing 25 which conaxis of rod 12 and with fines portions 19 and 20 of the wire closely within the respective recesses 14 and 15.

Since the channels 14 and15 and the peculiar conformation of the end of wire 13 can readilybe prepared prior to the assembling operation, and since no machine operations are necessary in the course of assembly, it

will be obvious that much time, labor, and expense is saved by the present invention. It has been found, moreover, that the Wire and handle do not tend to become misaligned or distorted in use and, consequently, all thrusts the :handle are transmitted along the axial line roflzthe" wire.
